FAQ
Choosing a Web Agency - FAQ
Ask about their development process, who will work on your project, how they handle revisions, what their timeline guarantee looks like, whether the price is fixed or hourly, who owns the code, and what post-launch support includes. Vague answers to any of these are a red flag.
Watch for: no portfolio or only template-based work, no clear process or timeline, hourly billing with no estimate cap, inability to explain technical decisions in plain language, no post-launch support plan, and pressure to sign before you have had all questions answered.
Never. A cheap website that does not convert, breaks often, or cannot be maintained costs far more in the long run. Compare total value: design quality, development approach, SEO inclusion, post-launch support, and the agency's track record of delivering on time and on budget.
Visit the actual live sites, not just screenshots. Check loading speed with PageSpeed Insights, test on mobile, look at the design quality and attention to detail, and see if the sites rank on Google. A portfolio of fast, well-ranking, well-designed sites says more than any sales pitch.
Freelancers can be great for small projects but risky for larger ones - they get sick, go on vacation, or take on too much work. Agencies offer team redundancy, broader skill sets (design + dev + SEO), structured processes, and ongoing support. For business-critical websites, an agency is usually the safer bet.
A Practical Guide to Finding the Right Web Partner
Hiring a web agency is one of the most consequential decisions a business makes, yet most companies choose based on a flashy pitch, a low quote, or a friend's recommendation. This guide is designed to help you evaluate web development agencies objectively, using the same criteria experienced CTOs and marketing directors use. Whether you are building your first business website or replacing a poorly built one, these principles apply.
Start by examining the agency's actual work. Visit live portfolio sites and test them: measure page speed, check mobile responsiveness, look at design quality and consistency, and see how the sites perform in search results. Then ask about process: how do they handle discovery, design, development, testing, and launch? A clear process with defined milestones protects both sides from scope creep and misaligned expectations.
The questions you ask before signing reveal more than the answers. Ask who specifically will design and develop your site (not just the sales team). Ask whether the price is fixed or hourly, what happens if the project runs over, who owns the source code, and what post-launch support looks like. Transparent agencies welcome these questions because they have clear answers. Evasive responses are your cue to keep looking.
Finally, consider the long-term relationship. Your website is not a one-time project - it needs ongoing maintenance, SEO work, content updates, and eventually a redesign. The best agency is one that will still be around and motivated to support you in two, three, or five years. At Kosmoweb, transparency and long-term partnership are not marketing claims - they are how we have built our reputation in Prague's web development market.
